Shobu Asagi

This is probably the hardest Jnat I’ve ever used. Straight razor edges off this one come up to a ridiculous level of sharp while also being extremely smooth. The line in the stone cannot be felt, it’s just a part of the stone that is a different color. The size and shape are perfect.

Lapping this stone took over an hour on an Atoma 400x but it was worth every second invested in getting this dead-flat. Stones that are both very hard and high-quality like this one are super rare. The only distraction here is the line and that’s purely a superficial concern.
